Answer this question truthfully
### Question: How to know you have Hemophilia?
### Response: If the patient is the first person in the family to have a suspected bleeding disorder, he or she will undergo a series of tests called a coagulation study. Once a disorder has been identified, other family members will need less testing to diagnose the disorder.
Tests to diagnose hemophilia A include:
Low serum factor VIII/ IX activity Normal prothrombin time (PT) Normal bleeding time (BT) Normal fibrinogen level Prolonged partial thromboplastin time (PTT)
